Hi! I understand your Staples app stopped recognizing you. To get this sorted out, can you tell me if the app fails to log you in, doesn't recognize your rewards account, or if it’s another specific issue with recognition? Also, have you tried any fixes so far? This will help me guide you better.

In the meantime, here are some common steps to resolve this kind of issue:

1. Sign Out and Restart: Try logging out of the Staples app completely, then close the app and reopen it. Sometimes, refreshing the session helps.

2. Check Your Credentials: Ensure that your username/email and password are typed correctly. If you suspect the password might be an issue, you can reset it via the Staples website.

3. Update the App: Make sure your Staples app is updated to the latest version available on your device. Outdated apps can cause recognition problems.

4. Clear App Cache (if applicable): Although cache clearing is easier on mobile devices, on Windows you can clear temporary files or reset the app via system settings.

5. Reinstall the App: Uninstall the Staples app and then download it fresh from the official source. This often clears out corrupt data causing recognition issues.

6. Try Logging in on Staples Website: Go to staples.com and log in through the website directly. If this works, the issue might be app-specific.

If you want, I can walk you through any of these steps or, if you have tried some already, let me know which ones and I’ll suggest more advanced troubleshooting.

Are you satisfied with this initial guidance?
